Water → Ethyl 3-(3-furanyl)-3-oxo-2-((4-(trifluoromethyl)phenyl)methyl)propionate

Participants

Reaction Steps

To a solution of ethyl 3-(3-furanyl)-3-oxopropionate (20 g, 110 mmol) in 1,2-dimethoxyethane (100 ml) was added sodium hydride (60% in oil, 4.4 g, 110 mmol) under ice-cooling and the mixture was stirred at room temperature for 30 min. To the reaction solution was dropwise added a solution of 4-trifluoromethylbenzyl bromide (26.2 g, 110 mmol) in 1,2-dimethoxyethane (50 ml) and the reaction solution was stirred at room temperature for 3 hrs. The reaction solution was poured into water (300 ml) and extracted with ethyl acetate (500 ml×2). The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was recrystallized from diisopropyl ether-hexane to give ethyl 3-(3-furanyl)-3-oxo-2-((4-(trifluoromethyl)phenyl)methyl)propionate (28.8 g, 77%).
